I have double checked, BOTH the PLM and the EZBridge report back exactly the same..
Looks like the problem is with the device being interrogated (the EZRain1)
I've run the same tests on other devices, as a result of the problems with the EZRain..
The only device I found that reports CORRECTLY is the EZX10RF.
The EZBridge (when being interrogated by an external PLM) responds the same way as the EZRain... the 2MSB is different though..
When it comes down to it, even though the devices don't follow spec, they are still distinguishable, unlike the legacy devices.
I'm trying to find a way to determine if I'm talking to a Switchlinc, or a Keypadlinc...
I'll let you know if I find a way...
